How to Use this Guide Use this guide to select the linear guide ball slides, rails and accessories that you need for your application.

Pages 6, 14, 22, 23, 24 and 33 provide identification numbers that you will need to order the components for your application.

If you have any uncertainties, or would like more detailed information about any aspect of linear guides, please contact your NSK representative at one of our locations listed on the back cover.

FEATURES Interchangeability of Rail and Ball Slide One important manufacturing feature of the Gothic Arch is the ability to make highly accurate measurements on both the ball slide and rail, allowing for tight tolerance control, resulting in interchangeability. This means that additions and/or replacement of ball slides is easily done.

High Load Capacity and Long Life NSK has developed an infinite ball recirculating type linear guide with the largest load capacity available (comparing equal size ball slides). This high load capability helps to ensure long life.

Compact Low Profile Type To minimize space, NSK has developed low profile linear guides to handle various applications.

Miniature and Miniature Wide Type Stainless Steel If light loads and corrosive conditions are present for your application needs, NSK can supply a miniature and miniature wide type linear guide in stainless steel. NSK’s built-in ball retainer system allows for easy installation and removal of ball slides.

Wide Type If your application requires low profile combined with high load, NSK offers the wide series linear guides.

Shock Resistant Design Another design feature of the Gothic arch is its ability to absorb vertical shock loads from above using four-row groove configuration. This design is favorable in case of unexpected accidents during installation, or the operation of equipment. The ball groove is designed to avoid edge loading under extreme loads, extending the life of the unit.

DF Arrangement 2 point contact

Normal Load

Shock Load

Normal load is carried on the top two grooves.

Shock load is carried by all four grooves.

Universal Slider NSK has incorporated both thru and tapped holes into one flanged slider for a combination of mounting applications. (EM/EMZ replaces EL/ELZ and FL/FLZ • GM/GMZ replaces HL/HLZ and GL/GLZ)

Ability to Butt Rails Tolerance of ball grooves on the ball slides and rails are controlled to allow for butting, giving you the flexibility of unlimited lengths. We can offer a stocked linear guide rail with versatility in assembling preloaded or clearance type ball slides.

K1™ Maintenance-Free Lubrication Units NSK has the K1™ Lubrication Units for all five series of interchangeable linear guides. These K1™ Lubrication Units are all available from stock.

Maximum Rail Length in One Section Available up to 4,000 mm.

Short Delivery Time We can ship from our large inventory, both standard and custom cut-to-length linear rails.

Fluoride Low Temperature Chrome Plating NSK has a plating for linear bearings and rails to cover conditions requiring wet, corrosive and clean room applications. NSK also uses industry approved armaloy coating. These are available from stock.

Accuracy Standard

Load Rating and Life

The accuracy standard of the NSK “High Load Capacity LH-Series” is shown in Table 1. With highaccuracy control of individual rail size and interchangeability, the accuracy of Table 1 can be maintained sufficiently even after addition or replacement of the ball slide.

The LH-Series is based on a design applying load from above. Therefore the dimension table shows the basic dynamic load rating C and basic static load rating C0 for the downward direction. If the load is applied laterally or upward refer to values in Table 2.

Accuracy Standard

Load Rating and Life

The accuracy standard of the NSK “Compact Low Profile LS-Series” is shown in Table 1. With highaccuracy control of individual rail size and interchangeability, the accuracy of Table 1 can be maintained sufficiently even after addition or replacement of the ball slide.

The LS-Series is based on a design applying load from above. Therefore the dimension table shows the basic dynamic load rating C and basic static load rating C0 for the downward direction. If the load is applied laterally or upward refer to values in Table 2.

Assembly

Mounting Procedure

Interchangeable ball slides are shipped on (disposable) plastic provisional rails as shown in Fig.-9.

1. Wipe off anticorrosive oil from the rail.

2. Since Alvania (AS2) grease is packed in the ball slide, you can use it as delivered.

3. Align the rail with bottom and side faces of provisional rail and while pushing the provisional rail lightly against the rail, slide the ball slide on to the rail (Fig.-9).

For cases where datum surface exists on the bed

Fig.-9 Assembly of Ball Slide with Rail

1. Lightly tighten the rail mounting bolts and then use the shoulder plate to secure rail datum surface against bed mounting surface (See Fig. 12).

2. Tighten rail mounting bolts to their recommended torques (Table 7). Tighten the bolts in an order which enables the wrench to help push the rail against the mounting surface (see Fig. 13 for example).

3. Mount the adjust side rail, as shown in Fig.-14, while checking rail parallelism. For the jig shown in Fig.-14, stability will be improved by mounting it on 2 ball slide.

Fig.-14 Parallelism Measurement with Jigs

4. If dowel pins are being used they should be installed at this step.

5. Position the ball slides at specified intervals and mount the table gently.

6. Tighten ball slide mounting bolts of datum side while pushing the table so that the table and ball slide mounting reference surfaces are in contact.

25

Indication of Installed Standard Side The datum face of each rail is indicated by a groove in the datum face or by an arrow mark on the end or top surface of the rail.

Lubrication Grease Lubrication NSK linear guides are packed with Alvania 2 grease and can be used as delivered. The replenishment frequency is recommended to be once a year, but adjust the interval depending on the operation conditions.

(1) To Change Direction of Grease Fitting 1. Remove the grease fitting with a wrench.

2. Wind some sealing tape on the thread of the fitting, then insert it and tighten. Be careful not to over torque when tightening into the side of the plastic bearing end cap.

Notes on Usage Separately packaged ball slide is mounted on a plastic temporary axis (disposable) as shown at left.

1. Wipe anti-rust oil from the rail.

2. Product is ready for use as is since Alvania 2 grease is sealed inside the ball slide.

3. Note the groove mark which identifies the datum faces of ball slide and rail above.

4. Move the ball slide, matching and slightly pushing the base and the side of provisional rail to the rail as in drawing at left.

(2) Change of Fitting Position in Front/Back Direction 1. Remove the plug from the grease fitting mounting hole face B shown in Fig.-9 with a hexagonal wrench.

2. Remove the grease fitting from face A and screw into hole face B. 3. In place of the removed fitting, insert the plug into the hole in the face A.

(3) Change Grease Fitting Position to Side Surface To mount the grease fitting on the end cap side face, or on the ball slide face, please consult NSK.

Oil Lubrication Oil piping can be connected to the tapped hole from where the grease fitting was removed. Piping joints are listed on page 13 and page 21. The recommended lubrication oil supply quantity per ball slide per hour Q is given by the following formula, where N is the rail width number.

Q= N (ml/hr) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . (5) 150
